My iPhone 4S was perfectly fine until this afternoon when WIFI just stopped working. It would simply not find any networks.
I then placed my phone on airplane mode and then turned it off. The WiFi sign was now dimmed and isnt able to get turned on or off.
Bluetooth just keeps on loading and is never giving me the option to turn it on...
I don't know if this has anything to do witht he IOS 6.1.3 since I have been reading some discussions and blogs about it. A lot of people seem to be having trouble with this.
I wonder if it is really a software issue.
On another note, if I want to take my phone for service, is it possible that it is taken in even though I have lost my receipt.
Thanks so much.
1. Change Network settings at Settings > General > Reset and/or
2. Restore the iPhone with iTunes as a new iPhone and not from the backup.
If no wi-fi thereafter or its selection is grayed out, the iPhone has a hardware problem. Seek appointment at the Genius Bar.
I've done that about 3 times already and it didn't work.
At one point I could turn the Wifi on but still didn't find any network when my laptop did.
Do you know if I can take it in and get it checked by apple withouth a receipt. I lost mine but according to apple.com my one year warranty is still working.
